Sorry if asking here is in itself insensitive, but I figured asking people who may have been in this situation what they would find least difficult (or most) might help me at least avoid a really obvious faux pas.
Straw poll? Face to face/phone/email? Should I mention that it was unintentional (she knows I wouldn't have been trying), or would that just add insult to injury?
Is a close friend, someone who I wouldn't in the normal course of events wait till 12 weeks to tell, so feel I need to do something about it soon or she'd feel that it was a bit weird when she eventually did find out; I just don't want to make things any harder for her just now than they are already.
